TECHNICAL BACKGROUND

Lighting arrangements based on rail systems, for example for lighting purposes in buildings, are already known. For example, systems have already been proposed in which electrical conductors for providing a supply voltage and control signals are integrated into a rail profile. Such rail systems include, for example, a number of light inserts of different types, for example spots or linear light inserts, which can also be combined

Furthermore, a lighting system is described in EP 3 336 420 B1, for example, which includes a channel for accommodating a lighting unit that can be inserted into it. A connector insertable into the channel is configured to electrically couple bus bar sections together. When inserted into the channel, the lighting unit and the connector can overlap inside the channel

This is a condition that needs to be improved.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of specifying a lighting arrangement that makes it possible to provide an indirect light component in a simpler manner. Furthermore, a coupling unit for the formation of a lighting arrangement should be specified, which makes it possible to couple with another component of the lighting arrangement, such as a

Component for indirect lighting, to accomplish in a simple manner. According to the invention this object is achieved by a lighting arrangement with the

Features of claim 1 and / or by a coupling unit with the

Features of claim 15 solved.

A lighting arrangement with a rail, at least one

nem indirect light module, and a coupling unit.

The rail is designed for coupling and/or at least partially accommodating at least one lighting module or at least one lighting unit and has an inner region in which a conductor device is provided along the rail at least for providing electrical energy for supplying the lighting module or the lighting unit. The indirect light module is designed to provide indirect lighting. The coupling unit can be coupled to the rail and is set up to receive at least electrical energy from the conductor device and to supply the indirect light module with electrical energy. In this case, the rail has a web which is designed as a delimitation of the inner area of the rail that is equipped with the conductor device. In the area of the web, the rail has a through-opening. The coupling unit has a contacting section that can be guided through the through-opening in order to electrically couple the indirect light-emitting module

to bring about with the coupling unit.

Furthermore, a coupling unit for a lighting arrangement, in particular such a lighting arrangement according to the invention, is proposed. The coupling unit can be inserted into a rail of the lighting arrangement and can be coupled to the rail. In this case, the coupling unit has a first contact device in order to make electrically conductive contact with conductors of a conductor device extending along the rail. Furthermore, the coupling unit has a contacting section which is designed to be inserted into a through-opening in a web of the rail when the coupling unit is inserted into the rail. A second contact device arranged on the contacting section is provided here to make electrically conductive contact with a contact device of another component and to electrically couple the coupling unit to the other component. For the other component

it can in particular be an indirect light module.

An idea on which the invention is based is that by providing a through-opening in a web of a rail and inserting a contacting section of a coupling unit into the through-opening, a significantly simplified supply of the other component, which is designed in particular as an indirect light module, is achieved. In particular, an advantageous simplification can be achieved if the other component with regard to the coupling

unit is to be placed on the other side of the dock.

The supply of the other components, in particular the indirect light module, therefore does not require any conventional, cumbersome cabling at a factory-predefined location, which is carried out, for example, on the construction site, but can be done by making the through-opening - for example as a prefabricated opening in the web, or through its flexible installation on the construction site — and the use of the through-opening for electrical coupling can be significantly simplified. In this way, the conductor device in the inner region of the rail can advantageously be used to supply the other components, and

the production of the contact requires in particular only a few manipulations.

Advantageous refinements and developments of the invention result from the further subclaims and from the description with reference to FIG

the figures.

In one configuration, the coupling unit and the indirect lighting module are set up for electrical coupling to one another in such a way that the indirect lighting module can be displaced relative to the coupling unit coupled to the rail along a longitudinal direction of the rail. This enables adjustments with regard to the position of the indirect light module along the rail even after the coupling unit has been inserted and the coupling unit and the electrical coupling have been electrically coupled

In a preferred embodiment, the contact section is designed as an extension of a body of the coupling unit. In particular, the contact section is arranged rigidly on the coupling unit. This can also lead to a simple

In some configurations, the amount of cabling required to supply the other component, in particular the indirect light module, can be significantly reduced

or cabling for this purpose can even be completely avoided.

In one embodiment, the coupling unit has contact elements, in particular punctiform contact elements, through the interaction of which with associated elongated contact elements of the indirect light module, the, in particular displaceable, electrical coupling to the indirect light module can be brought about. In particular, the contact elements of the coupling unit are provided on the contacting section of the same. For example, in the case of an indirect light module that is designed to be elongated, for example, contact elements that are designed to be elongated can be provided relatively easily on this module, and a comparatively compact contacting section becomes possible. Such an embodiment can require cabling

help to avoid and enables a particularly simple and quick installation.

In a development, the elongated contact elements extend with their longitudinal direction in a state of the indirect light module coupled to the rail along the longitudinal direction of the rail. This contributes advantageously to a simple

Chen and expedient sliding coupling.

In particular, the elongated contact elements of the indirect light module

More preferably, the elongate contact elements of the indirect light module are arranged on a side thereof that faces the coupling unit when the coupling unit is inserted into the rail and the indirect light module is coupled to the rail. This allows further simplification of the electrical

In particular, the functions of generating light and making contact with the contact elements of the coupling unit can thus be combined on the double-sided printed circuit board

According to another embodiment, the coupling unit and the indirect light module are set up to bring about the electrical coupling of these by means of cabling. Such a configuration can be implemented cost-effectively and, in particular due to the flexible positioning of the through-opening, can contribute to the coupling even when using cabling

in a simple, uncomplicated way.

In further developments, the passage opening of the rail, which is provided for the coupling of the coupling unit and the indirect lighting module, can already be made in the rail at the factory or on site during the assembly of the lighting arrangement. In particular, the through-opening can be introduced at any point along the web by methods that are simple for a fitter or a specialist, for example by drilling. This allows a high degree of flexibility in positioning the coupling unit(s) and lighting

Such an arrangement of the conductors further facilitates the production of the electrical contacting of the coupling unit and the indirect light module and can be compact and space-saving.

In one configuration, the conductor device is also set up to provide a control signal, with the coupling unit being set up to receive the control signal from the conductor device and to transmit a signal to the indirect light module for controlling the same and/or to control the indirect light module. In particular, the coupling unit can be set up to forward the received control signal to the indirect light module, or be set up to interpret the received control signal and, based on the received control signal, to control the indirect light module and/or based on the received control signal to transmit to the indirect light module signal and to that

In a development, the coupling unit can be designed as a connection unit. The connection unit can be set up, for example, to forward electric current and in particular also the control signal from the conductor device to the indirect light module, in particular to forward it essentially unchanged. This can be advantageous, for example, if the electrical energy provided by the conductor device, for example in the case of a DC voltage selected as low voltage, can be used for operating the indirect light module without further conversion. In addition, the above configuration can also be useful, for example, if the indirect light module directly uses or interprets the control signal present on the conductor device.

In a further embodiment, the rail can be provided for a suspended attachment of the same, in particular to a ceiling or another part of a building or to another structure.

In one development, the indirect light module can be inserted into a receiving area of the rail, which is formed in a cross-sectional profile of the rail, facing away from the inner area. Here, the indirect light module can be arranged in a simple, reliable, accurate and aesthetic manner on the rail to the indirect lighting, especially up to a ceiling

In one configuration, the receiving area is a rear area of the rail when the lighting arrangement is in use, with the rear area and the inner area being formed adjacent to one another and through the web

In one configuration, the indirect light module is set up to be electrically coupled to at least one extension indirect light module in such a way that the extension indirect light module mediates via the indirect light module

can be supplied with electrical energy by the coupling unit.

In one development, the indirect light module is set up to be coupled to the extension indirect light module in such a way that the extension indirect light module is controlled via the indirect light module in accordance with those control signals that are used to control the indirect light module

In particular, it can be provided that the extension indirect light module can be controlled by means of a signal that can be provided by interpreting the control signal provided on the conductor device by the coupling unit or by the indirect light module and from the indirect light module to the

The provision of one or more extension indirect lighting modules thus enables the provision of elongated indirect lighting, for example an indirect light band, of great length on a rail, with a separate coupling unit not being required for each module of the indirect lighting. Instead, the energy supply and preferably the control of indirect and extension indirect light modules that are lined up in a row and are electrically coupled to one another succeed via a common coupling unit. This can help reduce costs

DESCRIPTION OF EXEMPLARY EMBODIMENTS

A first lighting arrangement 1 is shown in FIGS. 1, 2. The lighting arrangement 1 is formed with components which are part of a modular track lighting system. The rail lighting system is designed in such a way that linear lighting modules and/or low-voltage rails and/or spotlights can be accommodated and combined in one rail. Additional lighting units can be coupled to the low-voltage rails, which, like the linear lighting modules and spotlights, are preferably used for direct lighting. In addition, the track lighting system includes the possibility, in some variants, of providing indirect lighting by means of one or more indirect lighting modules. Advantageously, not every single, insertable luminous component has to be included

be equipped with its own converter.

It should be mentioned that the rail for installation in a ceiling, a mounting on a ceiling and / or hanging from the ceiling of a room, or from

another construction, can be formed.

First, a lighting arrangement 1 with direct lighting by means of a linear lighting module 11 is described. The arrangement 1 comprises a rail 3 which is open towards the visible side S, in a fully assembled position in particular at the lower side, and a first inner region 4 and one lying in the rail 3 above the first region 4 and further to a facing away from the visible side S back of the rail 3 arranged towards second, inner

Region 5 has. On the back, in the fully assembled position, especially in a

In the upper area of the rail 3, the second area 5 is closed off by a web 3a, from the opposite ends of which flanges or side walls 3b of the profile 3 extend. Inner longitudinal ribs 3c, 3c' of the profile 3 delimit the regions 4, 5 from one another, with an intermediate space between the longitudinal ribs 3c, 3c' providing access to the second region 5 from the first region 4. The rail profile 3 is cross-sectional except for the end sections of the longitudinal ribs 3c, 3e'

with respect to a longitudinal median plane of the profile 3 symmetrical.

In the second area 5, busbars are arranged on both sides along the rail profile 3 and parallel to its longitudinal direction L, each with three poles or conductors and form a conductor device 6 with a total of six conductors 6a, 6b, of which four conductors 6a for providing electrical energy and two mutually oppositely arranged conductors 6b are provided for the provision of control signals. Three of the conductors 6a are preferably each phase conductors to provide three different electrical phases and a fourth of the conductors 6a

formed as a neutral conductor.

In a variant, see FIG. 25, the conductor device 6 could alternatively provide, for example, five poles or conductors 6a, 6b on both sides of the second area 5 and thus a total of ten conductors 6a, 6b in order to be able to switch additional emergency lights in a separate phase . Figure 25 illustrates a rail with such an alternative conductor arrangement. Again, in area 5 there are two contactors

NEN, and a total of at least two conductors 6b for control signals provided.

For example, a DALI signal for control is provided by means of the conductor 6b. A control signal based on other control or dimming methods

is also conceivable.

In Fig. 1 and 2, the conductors 6a are therefore provided for supplying luminous components with electrical energy and are supplied with electrical current from a feed unit, not shown in detail, preferably alternating current at mains voltage, around 220-240V, for example 230V, and a mains frequency of, for example 50 Hz. In the following, this is to be described with the term "high voltage".

be drawn.

In the track lighting system and the arrangement 1 luminous components are provided, which are operated with electrical energy at a much lower voltage, such as a DC voltage less than 60V, for example

way from 48V. In the following, this will be referred to as "low voltage".

The second area 5 of the rail 3, designed as an upper interior space, is designed to accommodate an adapter unit 7, the adapter unit 7 having a converter which converts the high voltage of the conductors 6a into low voltage for supplying the luminous components, in Fig. 1, 2 of the luminous module 11 , converts and thereby provides the type of current required by the luminous components at the low voltage. The converter is arranged inside the adapter unit 7 . Preferably, the adapter unit 7 also has a device not shown in detail in the figures, which makes it possible to select the electrical phases provided by the conductors 6a to be used and to switch the lighting unit 11 on with the intermediary of

to couple the converter with the selected phase to the power supply.

In the installed state, the adapter unit 7 is for the most part accommodated within the second area 5 and essentially has the basic shape of an elongated cuboid with beveled longitudinal edges on the side of the web 3a that faces the web 3a in the installed state. Here, the adapter unit 7 is slim and space-saving. For example, see FIG. 2, a height H7 of the adapter unit 7 can be about H7=28 mm and a width B7 of the adapter unit 7 can be about B7=14 mm. In particular, the ratio H7/B7 is therefore approximately 2. A length of the adapter unit 7, see FIG. 1, can be approximately L7=300 mm. Deviations from these values for H7, B7 and/or L7 are possible in variants, for example H7, B7 and/or L7 could each be 2 mm up or down from the

deviate from the stated values.

In the area of the longitudinal side surfaces of the adapter unit 7, the latter has a first contact device 1013 with contact elements 13, which can be moved or folded out of the outer surface of the adapter unit 7 in order to contact one of the conductors 6a in an electrically conductive manner. Also for the acceptance of the tax

tion signal, contact elements 13 can be provided, for example as shown in Fig.

4 outlined as two central contact elements 13 of a movable arrangement of six contact elements 13, three of which can protrude from one of the two longitudinal sides of the adapter unit 7. In this way, the adapter unit 7 can be electrically coupled to the conductor device 6 in order to receive electrical energy and control signals from the conductor device 6 . The contact elements 13 can be folded out or folded in by a mechanism that can be actuated by a fitter or operator. In particular in the case of a ten-pole rail, such as in Fig. 25, the contact device 1013 is not necessarily provided with contact elements 13 for contacting each of the ten conductors 6a, 6b, but can nevertheless be provided with, for example, four or six contact elements 13

be equipped.

The adapter unit 7 of FIGS. 1, 2 can be placed anywhere along the rail 3 in the inner region 5 essentially at any point. In addition, the adapter unit 7 used in the area 5 can be moved in the longitudinal direction L if

the contact elements 13 are folded in and do not contact the conductors 6a, 6b.

Furthermore, mechanical engagement elements 14 are provided in the area of the two longitudinal side surfaces of the adapter unit 7, which can also be moved or folded out of the outer surface in order to mechanically secure the adapter unit 7 in a detachable manner by reaching behind the inner longitudinal ribs 3c, 3e' of the rail 3. In addition, for example, ratchet or clip-like further engagement elements can be provided which provide a temporary, releasable fixation to facilitate the

enable assembly.

In FIGS. 1, 2, the second area 5 is delimited towards the first area 4 by the inner longitudinal ribs 3c, 3e' of the rail 3. These ribs 3c, 3e' form a kind of two-part intermediate wall, in the central area of which an intermediate space remains along the entire length of the rail profile 3 as a passage for inserting the adapter unit 7. In Fig. 1, 2 the flanges or side walls 3b of the rail 3

For the lighting arrangement 1 of FIGS.

rect lighting is formed.

The lighting module 11 also has a double-sided printed circuit board ("PCB") 21 on the upper side of the same when installed, on the outward-facing main surface of which strip-shaped contact elements 18 are designed as conductor tracks and for electrical coupling to the adapter unit 7 via the contact elements 17 for the purpose serve the energy supply and for control purposes. On the other main surface of the circuit board 21, light generating devices formed as LEDs are arranged. Other electrical and / or electronic devices for the operation of the LEDs, as well as conductor tracks, can also

the circuit board 21 may be arranged.

When assembling the lighting arrangement 1, the adapter unit 7 is first inserted from below into the second region 5, electrically coupled to the conductor device 6 by means of the contact elements 13, for example by rotating an actuating element, and additionally secured mechanically by means of the elements 14, for example. The light module 11 is then inserted from below into the first area 4 below the adapter unit 7 and, with the aid of latching or clipping devices 16, is latched or snapped into longitudinal grooves 4a behind further longitudinal ribs of the rail 3.

The latching devices 16 together with corresponding longitudinal ribs and longitudinal grooves 4a are designed in such a way that the assembly 2 can be clipped/latched into the area 4 with only relatively little force, and also again from below out of the rail 3.

is extendable. Here, in particular, a fixation of the lighting module 11 in

Longitudinal direction L not provided in the arrangement 1. This and the appropriate force of the latching/clipping devices 16 enable the longitudinal displacement of the

Light module 11 in the longitudinal direction L, which position adjustments are possible.

The current consumption by the light-emitting module 11 is made possible by means of a number of conductor tracks 18 attached to the printed circuit board 21, which each come into electrically conductive contact with an assigned one of the punctiform contact elements 17. Here, the strip-shaped contact elements 18 are provided on a side of the assembly 2 that faces the adapter unit 7 and extend in the longitudinal direction L of the rail 3 when the assembly 2 is inserted into the first, lower region 4 . The light module 11 can also be moved within the rail 3 in the longitudinal direction L even after the electrical coupling, at the same time a power supply is ensured as long as the circuit board 21 is on a

any point under the customers 17 of the adapter unit 7 is located.

The control signal, for example a DALI signal or a control signal based on another protocol, is taken from the conductor device 6 by the adapter unit 7 and the lighting module 11 is operated on the basis of this control signal. In the arrangement 1, the control signal can be interpreted by devices in the adapter unit 7, an output signal for controlling the lighting module 11 can be generated and the output signal can be transmitted to the lighting module 11 via one or more of the contact elements 17. Alternatively, it can be provided that the control signal picked up by the conductor device 6 is forwarded from the adapter unit 7 via one or more of the contact elements 17 to the lighting module 11 and through devices in the lighting module 11

is interpreted.

The track 3 can be formed with multiple track sections that connect together to form a longer linear or angled system of selectable length that can accommodate a variety of luminous components of the same or different types. If the rail 3 is constructed with a plurality of sections joined together, each with busbar pieces arranged therein to form the conductor device 6, they can form the conductor device 6

the busbar pieces in the second area 5, thus in the high-voltage area,

with intermediate or connecting pieces (not shown in the figures) for electrical

mechanical coupling of the corresponding conductors 6a, 6b are electrically connected.

The assemblies 2, 12 are each equipped at the front with connection devices 15 provided for this purpose, such that the assembly 2 can be electrically coupled to one of the other assemblies 12 at both ends of the assembly. In this way, the assembly 2 and, via this, the assembly(s) 12 are supplied with electrical energy provided by the adapter unit 7

supplied, in particular with direct current at low voltage.

Thus, with a longer lighting arrangement 1', not every section of the rail 3 and not every lighting module 11, 11a requires a separate adapter unit in the upper (high-voltage) rail profile inner area 5. In Fig. 3, several lighting modules 11, 11a, for example a total of three modules, can be a common

Men adapter unit 7 are supplied.

In addition, the modules 2, 12 are controlled and operated according to a master-slave principle. The module 2 directly coupled to the adapter component 7 is regarded as the “master”, to which the other module(s) 12 indirectly coupled to the adapter unit 7 via the module 2 and the devices 15 are subordinated as “slaves”. is. The interpretation of the control signal applied to the conductors 6b, for example as a DALI signal, can be carried out by the adapter unit 7 or the first assembly 2 ("master"), with an output signal generated on the basis of the control signal from the adapter unit 7 or the assembly 2 üner the device 15 is passed on to the "slave" module(s) 12. In both cases, the assemblies 2 and 12, and therefore the light modules 11 and 11a,

via a common address, for example a common DALI address,

spoken, this address is thus assigned to the adapter 7 or the module 11 and indirectly to the coupled modules 11a. The extension light module

11a receives power and control signals corresponding to the first module 11.

At the same time, the assemblies 2, 12 used can be moved together along the rail 3. Advantageously, the adapter component 7 in the high

tension area 5 cannot be released and repositioned.

The light-emitting module 11a of FIG. 3 is designed analogously to the light-emitting module 11, the printed circuit boards of the second and further light-emitting module 11a not necessarily being double-sided, but being single-sided and thus being able to be designed more cost-effectively. The printed circuit board can supply power and drive the LEDs on the inboard main surface of the printed circuit board at the light-emitting module(s) 11a and the power and signal supply via the device(s)

15 enable.

In particular, the modules 11, 11a, which together - are supplied directly (“master”) or indirectly (“slave”) by an adapter 7, in the same, by means of the

Adapter unit 7 selected electrical phase connected and powered by this.

5-13 show a lighting arrangement 1a, 1a' and variants thereof. The arrangement 1a' of Fig. 5 has a rail 3 corresponding to that in Figs. 1-3. Lighting units 211a and/or 211b outlined as examples in FIG

an assembly 2 with a smaller rail 9 coupled to the rail 3.

The second, smaller rail profile 9 is accommodated in the first area 4 . The second, smaller rail 9 is supplied with low voltage by an adapter unit 7' located above it in the installed and operating state and is designed for at least partially accommodating and/or coupling to the lighting units 211a, 211b—only shown schematically. Furthermore, the rail 9 allows the power supply of the lighting units 211a, 211b, also the rail 9 can provide control signals for the lighting units 211a, 211b, the lighting units 211a, 211b, for example, with suitable devices for electrical

and further equipped for mechanical coupling to the rail 9, for example

are. The lighting units 211a, 211b are preferably connected to the rail 9

slidably coupled and intended in particular for direct lighting.

Furthermore, according to an exemplary embodiment, the lighting arrangement 1a' has a coupling unit 8', which is also referred to below as a connection unit 8' and which enables an electrical coupling of the rail 9 and the adapter unit 7'. The subassembly 2 that can be accommodated in the first region 4 of the rail 3 is formed here with the rail 9 and the connecting unit 8'. It is preferably provided that the assembly 2, in particular the rail 9, can be latched to the rail 3 for mechanical attachment or can be clipped into the rail 3, for which purpose suitable means not shown in the figures can be provided. The mechanical attachment of the assembly 2 formed with the rail 9 and the connecting unit 8' is analogous to the latching or clipping of the assembly 2 in the arrangements 1, 1' in such a way that even after latching or clipping, the rail 9 and the Connection unit 8 'in the longitudinal direction L of the rail 3 is possible. Also in the arrangement 1a', the engagement of the assembly 2 with the rail 3 and the disengagement from this engagement requires relatively little force, making the engagement and disengagement smooth and quick

can be done.

The adapter unit 7′ is constructed like the adapter unit 7 in terms of basic shape and dimensions, mechanical fixing in the outer rail 3 and electrical coupling to the conductor device 6, so that reference is made to the above statements in this regard. A converter is arranged inside the adapter unit 7'

net.

In contrast to the adapter unit 7, the adapter unit 11 is not equipped with selective current collectors for the supply of light modules on its lower side, which faces the visible side S in the assembled state. Instead, the adapter unit 7' of Figs. 5-13 has on the underside of the adapter unit 7', i.e. that side which faces the rail 9, when the adapter unit 7' and the assembly 2 comprising the rail 9 and the connecting unit 8' in the rail 3 are used, a contact device 1027 with several strip-shaped contact

elements 27 on. The contact elements 27 can when inserting the assembly 2

are brought into the rail 3 in each case with an associated contact element 28 of the assembly 2 in electrically conductive contact. When the adapter component 7' is inserted into the second area 5, the strip-shaped contact elements extend

elements 27 with their longitudinal direction parallel to the longitudinal direction L of the rail 3.

The first low-voltage rail module, which can be inserted under the adapter unit 7' in the shown section of the rail profile 3 and forms the assembly 2, has a through-opening 10' on the upper side of the rail 9 when installed, the through-opening 10' being in a web 9a of the rail 9 is introduced. After inserting the adapter unit 7 'and the assembly 2 in the rail 3 is the

Web 9a facing the adapter unit 7'.

A contact device of the connection unit 8 ′ is formed with the contact elements 28 . The several contact elements 28 of FIGS.

Section 8a 'executed.

By inserting the contact section 8a' into the through-opening 10', the punctiform contacts 28 of the connection unit 8' can each be electrically connected to one of the conductor tracks 27 of the adapter 1/' mounted thereabove

in order to electrically couple the assembly 2 to the adapter unit 7'.

The connector 8' serves as a coupling unit and subsequently ensures the supply of the subassembly 2 designed as a low-voltage rail module. Here, the rail 9 is provided with a conductor device 26 having low-voltage conductors 26a and control signal conductors 26b along the longitudinal direction of the rail 9. FIG. A cross section of the rail 9 is shown in Fig. 9 and also in the variant

ante of FIGS. 5, 6 provided in this form and equipment.

In this way, the low-voltage rail modules 2 are intended to receive and supply power to the lighting units 211a, 211b to be operated at low voltage, and to supply the lighting units 211a, 211b on the rail 9

control signals.

In particular, it is provided that the conductor 26a of the conductor device 26 in the interior of the rail 9 via the adapter unit 7 'and the connection unit 8' with electrical energy at low voltage, for example a direct voltage of 48 V, and with one or more control signals, for example a DALI

signal to be supplied.

The provision of the electrical current at low voltage by means of the adapter unit 7', based on the provision of mains voltage via the conductor device 6, takes place by means of a converter of the adapter unit 7' as described above for the arrangements 1, 1'. The low voltage for the power supply of the lighting units 211a, 211b is then forwarded to the connection unit 8' via two of the contact elements 27, 28, for example. Also choosing one

electrical phase using the adapter unit 7' is possible as described above.

Control signals provided on the conductors 6b of the conductor device 6, such as a DALI signal, are passed on unchanged to the connection unit 8' in the arrangement 1a' via one or more additional, corresponding ones of the contact elements 27, 28.

directed.

For example, one conductor 26a per side for the power supply and one further conductor 26a for the control can be provided on both sides of the inner area 9b of the rail 9 . The lighting units 211a, 211b that can be used there can in particular be addressed separately with control signals, for example

via own, separate DALI addresses.

The connection unit 8' is set up to receive the electrical energy and control signals from the adapter unit /7', and the electrical energy received via contact elements 27, 28 into the conductors 26a of the conductor device 26 of the rail 9, as well as from the adapter unit 7' via the further control signals forwarded to the contact elements 27, 28 into the conductor 26b. For this purpose, the connection unit 8 ′ has a contact device for the electrical coupling to the conductor device 26 . Furthermore, the connection unit 8 'with

the rail 9 of the assembly 2 mechanically latched or clipped.

Variants of the lighting arrangement 1a' according to further exemplary embodiments are shown in FIGS. 7-13. Except for the differences described below, the above statements relating to FIGS. 5, 6 also apply to the lighting arrangements

1a, 1a" of Fig. 7-13 application.

The lighting arrangement 1a of FIGS. 7-12 again has a rail 3, an adapter unit 1' and an assembly 2, with lighting units, e.g. 211a, 211b, being coupled to the rail 3 by means of the assembly 2. With regard to the design of the rail profile 3 and the adapter unit 7' and their function

reference is made to the explanations above.

In the variants of FIGS. 7-13, the subassembly 2 again comprises a second rail 9 with a conductor device 26 arranged in its inner area 25, which is divided into two and arranged on both sides of the inner area 25, see FIG

Connection unit 8, shown enlarged in Fig. 12.

The connection unit 8 in Figs. 7-13 has an elongated box-like external shape and is designed to be arranged substantially entirely in the inner region 25 of the rail 9, such that the conductors 26a of the ladder device 26 are located to the side of the connection unit 8, cf Figures 9-11. A first contact device 1030 with contact elements 30, see FIG. 12, is set up to make electrically conductive contact with the conductors 26a, 26b of the conductor device 26 extending along the rail 9 when the connection unit 8 is inserted into the inner region 25 . Elastically resilient latching elements 31 serve to clip the connecting unit 8 into the rail 9 in a preferably detachable manner

mechanical coupling of components 8 and 9.

The connection unit 8 has in Fig. 7-13 also the function of a coupling unit 8, which the electrical coupling of the rail 9 with the adapter unit 7 'for

Enables transmission of power and control signals. The connection unit 8 has a contacting section 8a, which is inserted into a through-opening 10 in the web 3a of the rail 3 when the coupling unit 8 is inserted into the rail 9.

will lead. There is a second contact device 1028 on the contacting section 8a

with—in FIG. 12 three by way of example—punctiform, pin-like or pin-head-like contact elements 28 are provided. The contact elements 28 are designed and arranged for this purpose, each with a corresponding one of the strip or sheet-like contacts

ELEMENTS 27 of the adapter unit 7' to make electrically conductive contact.

The contacting section 8a is in Figs. 7-13, in contrast to the plate-like contacting section 8a 'in Fig Contact elements 28 on. An outer outline of the contacting section 8a preferably corresponds to an inner

cross-sectional shape of the through hole 10.

It should also be noted that in FIGS. 7-11 and 13 the adapter unit 7' is provided with a projection 7a' approximately centrally in relation to its longitudinal axis and on its upper side which points towards the web 3a of the rail 3 in the assembled state. This can be part of a body and/or housing of the adapter unit 7' and, in other variants, can be equipped with contact elements instead of the contact elements 27, although in Figs. 7-11, 13 there are no contact elements on the projection 7a'. Alternatively, the projection /a' could be omitted from the adapter unit 7'.

be sen.

In a variant of the arrangement 1a, at least one further subassembly 12 can be provided, which is supplied via the subassembly 2 with electrical energy and control signals that are provided by the adapter unit /7'. Such a lighting arrangement 1a" is shown in Fig. 13. Similar to the assembly 2, the assembly 12 in Fig. 13 has a rail 9 with which one or more lighting unit(s), e.g. 211a, 211b (not shown in Fig. 13 ), can be coupled and/or can be accommodated at least in sections by the further rail 9. The extension rail 9 of the assembly 12 in Fig. 13 also has a conductor device 26 analogous to the assembly 2 in Fig. 5-12. In the area of a joint 1202 are the assemblies 2, 12 coupled to each other such that the corresponding conductors 26a, 26b of the two rails 9 at their adjacent

front ends are each electrically in contact with each other. For this can

for example, suitable trained coupling pieces (not shown).

be provided at the joints 1202.

In this way, a plurality of low-voltage rail modules in the form of subassemblies 2, 12 can be inserted into the rail 3 adjacent to one another and electrically connected. The assembly 12 of FIG. 13 has no connection unit 8 or 8'. It is thus sufficient to couple only a first low-voltage rail module, i.e. the assembly 2, to the high-voltage rail 3 in an electrically mediated manner via the adapter unit 7'. The low-voltage rail modules 2, 12 are all switched together in the same phase, which can be selected by means of the adapter unit 7'. Electric current for supplying the lighting units 211a, 211b and control signals are passed on via the conductors 26a, 26b at the coupling point 1202, which means that the assembly 12 is located on the extension rail 9

Lighting units can be controlled individually via their own addresses.

It can be seen from FIG. 13 that the rail 3 can be formed with a plurality of rail profile sections connected to one another at the ends in order to create a longer linear system, for example by means of suitable connecting pieces. Not every section of the rail 3 and not every rail section 9 requires a separate one

Adapter unit 7' in the upper area 5.

The arrangements 1a, 1a′, 1a″ each also allow, after the insertion of the adapter unit 7′ and the assembly 2 and possibly the assembly 12 into the rail 3, a displacement of the assembly 2 or the assemblies 2 and 12, inclusive

Rails 9 and connection units 8 and 8', respectively, relative to the adapter unit 7'.

14-18 show a lighting arrangement 1b according to an exemplary embodiment and a variant 1b' of the same, which can be fixed in a suspended manner and, in addition to luminous components for realizing direct lighting, can be equipped with indirect lighting. The lighting arrangement 1b, 1b' of FIGS. 14-18 can, for example, be suspended from a ceiling of a room or another part of a building or from another structure. The indirect lighting is in the arrangements 1b and

1b' implemented in the manner described below.

The lighting arrangement 1b, 1b' comprises a rail 3", which, analogous to the rail profile 3 in FIGS. 1-3, 5-13, has an area 4 and an inner area 5, the design and function of which are described above differs from the rail profile 3 in that the rail 3" also has a receiving area 44 on a rear side facing away from the visible side S, and thus on the rear of the web 3a. The receiving area 44 is in the cross-sectional profile of the rail 3" as a flat , Formed away from the second region 5 channel. The cross-sectional shape of the rail 3" is essentially symmetrical to a longitudinal center plane, except for the end sections of the

Longitudinal ribs 3c, 3c' that differ.

The receiving area 44 serves to receive a subassembly, which can be used as an elongate indirect light module 40, which is inserted into the receiving area 44 and in the installed state essentially upwards, ie for example in the direction

the ceiling of the room, can emit light.

The rail 3" in Fig. 14-18 is equipped with a three-phase, or alternatively a five-phase, conductor device 6 set up for mains voltage, analogous to that described above for the rails 3, 3'. The web 3a delimits the one equipped with the conductor device 6 inner area 5 upwards and thus separates the receiving area 44 from the inner area 5. Towards the top, i.e. to the rear side of the rail 3" opposite the visible side S", this is provided with one or

several through openings 50, see Fig. 17, provided in the web 3a.

Also provided is an adapter unit 7" that can be inserted into the rail 3" analogously to the adapter units 7, 7', which is designed analogously to the adapter units 7, 1/' with regard to the basic shape, mechanical fixation and electrical coupling in the area 5

with differences described below. In addition to the first contact device 1013, the adapter unit 7" has a

second contact device 1017a with selective contact elements 17a on the upper

side of the adapter unit 7". Here, the contact elements 17a are pin-like or

designed like a pin head and protrude from an upper surface of a projection-like contacting section 7a", which can be designed essentially like the projection /7a' from Fig. 13. The contacting section 7a" is essentially in the middle in relation to the longitudinal extension of the adapter unit 7". this is arranged and on the web 3a pointing away from the visible side S when in use

facing top of the adapter unit 7 "provided.

The contact section 7a” is for the electrical coupling of the indirect light module

40 and the adapter unit 7" can be inserted into the opening 50. Thus, the contact elements 17a, see Fig. 14, can protrude through the opening 50 and upwards out of it. A body section of the contacting section 7a" preferably fills the through-opening 50 substantially , causing this after insertion

of the adapter unit 7" is closed.

Like the adapter unit 7, 7', the adapter unit 7" can basically be freely positioned along the rail 3" by selecting a suitable opening 50 or making the opening 50 in the desired longitudinal position, but after inserting the

Contacting section 7a" can no longer be displaced longitudinally into the opening 50.

The first indirect light module 40, which can be slid into the rail 3", has a double-sided printed circuit board 41 ("PCB"), which is electrically coupled to the protruding contact elements 17a of the adapter unit 7" on its underside via a contact device 1047 having web-shaped or strip-shaped contact elements 47 can be. Further indirect light modules can each be inserted as an extension indirect light module 40a on the front side adjoining the first indirect light module 40 in the receiving area 44 and connected to the first indirect light module 40 according to a master/slave principle, with the indirect light module 40 being able to be regarded as the “master”. The connection can be made at a joint 4040, see FIG. 18, by means of connecting devices that are not shown in detail. The other indirect light modules 40a or "slaves" can have at least one-sided printed circuit board instead of the double-sided printed circuit board 41,

which can contribute to cost savings and simplified production.

An electrical supply of the indirect light module 40a is mediated via the indirect light module 40, where z. 1-4, a low voltage for the operation of the indirect light modules 40, 40a is provided by the adapter unit 7", which contains a converter. The adapter unit 7" can also be used to supply the power for the indirect light modules 40 , 40a, with the interposition of the converter, to be used, from the conductor device 6

provided electrical phase can be selected as described above.

The control of the indirect light modules 40, 40a is made possible in a similar manner to the direct light modules 11, 11a, with the indirect light modules 40, 40a being addressed via a common address, e.g. a DALI address, and being controlled together. The control signal provided on the conductors 26b of the conductor device 6 is interpreted by devices in the adapter unit 7" or alternatively by devices on the circuit board 41 of the "master" indirect light module 40 and, based on this, an output signal is generated for the controller, with the contact device 1017a for example for the transmission of the output signal generated on the basis of the interpretation of the control signal in the adapter unit 7" or for the forwarding of the control signal picked up by the adapter unit 7" from the conductor device 6. In both cases, the output signal resulting from the interpretation is output at the junction 4040 The output signal can be transmitted, for example, by means of a pulse width or

Be implemented pulse-pause modulation.

Cumbersome, separate cabling of the indirect light module 40 on the construction site can be avoided with the aid of the contact devices 1017a, 1047 described above and their interaction. A comparatively small through opening 50 is made in the area of the upper side of the rail 3" in the web 3a. The opening 50 can either be prefabricated or flexibly made at the desired position on the construction site. The contact elements 13 can initially be moved and placed freely Adapter 7" is then positioned in rail 3" under recess 50. Indirect light modules 40 can then, for example, be quickly, variably

be inserted easily and flexibly. In addition, remains for the indirect light module 40, and

possibly further indirect light modules 40a as "slaves", with a given electrical coupling, displaceability in the longitudinal direction L relative to the adapter unit 7" is also possible. For example, a further module 40a can be provided at each end of the module 40.

be seen, with an indirect light strip of greater length is also conceivable.

The adapter unit 7" serves in the manner described above as a coupling

ment unit 7" for coupling the conductor device 6 to the indirect lighting module 40.

The adapter unit 7" is set up as "slaves" for the supply of the indirect module 40 and, in the case of the arrangement 1b', other indirect modules 40a in the receiving area 44. In addition to the adapter unit 7", Fig. 14-18 shows another, in Fig. 15, 17, 18 not visible adapter unit 7 in the inner region 5 of the rail 3" and designed as described with reference to Figs Modules 2, 12 are supplied analogously to Fig. 1-3 in order to implement direct lighting by means of the lighting arrangement 1b, 1b', i.e. in particular starting from the visible side S into the spatial area below Example, continuous, direct and indirect light bands are generated at the same time, which are separately along the

Rail 3" can be moved.

14, 16 shows the end face of the rail 3" with two adapter units 7, 7" by way of example—one for direct and one for indirect modules—whereby, with the exception of the contact elements 17, only the foremost adapter unit 7" is visible

and the adapter unit 7 arranged behind it is covered.

As with the lighting arrangements that were described above with reference to FIGS. 1-13, in the exemplary embodiment of FIGS Module(s) 2, 12 is provided as a front area 4 of the rail 3" when the lighting arrangement 1b, 1b' is in use. The front side of the lighting arrangement 1b or 1b' corresponds to its visible side S, in particular

Special the underside in a mounted state.

The receiving area 44 for at least partially, preferably essentially completely, receiving the indirect lighting module 40 and, if applicable, the extension indirect lighting module 40a is designed as a rear area 44 of the rail 3". The receiving area 44 and the inner area 5 are therefore on different sides of the web 3a, with the inner area 5 being provided between the web 3a and the area 4. The rear-side receiving area 44 and the inner area 5 are thus in the embodiment of FIGS

adjacent to one another and in this case delimited from one another by the web 3a.

It should be mentioned that the contact devices 1017a, 1047 described above with reference to exemplary embodiments enable a simple and quick, displaceable electrical coupling, which is advantageous during assembly only

requires little effort and time and is also space-saving.

In a modified variant, however, the contact devices 1017a, 1047 can be replaced by a cable connection, with a sufficient cable length being provided to enable the indirect lighting module 40 and, if applicable, the extension indirect lighting module 40a to be moved relative to the adapter unit 7" used. The cable connection can For example, be formed with a flexible cable that at one end thereof with the contact portion 7a "and at its other end with the indirect light module 40 is connected and through the

Opening 50 extends.

Some possibilities are shown above to construct a lighting arrangement on the basis of the rail lighting system described above, with the different assemblies, lighting modules, lighting units, indirect lighting modules and rail profiles described above being able to be combined in many ways in order to meet the lighting requirements in different applications, depending

because to match.

In particular, the indirect light module(s) 140, 140a from FIGS. 14-18 can be combined with the direct light modules described with reference to FIGS. 1-13

11, 11a or lighting units 211a, 211b combined in a variety of ways

will. In this way, for example, both directly and indirectly illuminating light bands can be realized which, when inserted, can be moved independently of one another with respect to the adapter unit provided in each case

7" or 7 or 7'.

As described above, there is no separate adapter unit for extension rails 9, see FIG. 13, or extension modules 11a, 40a, see FIGS

necessary.

However, a specially provided adapter unit is preferably provided for each of the differently configured assemblies 2, 12 and for the indirect lighting. For the lighting modules 11, 11a, for the low-voltage rails 9 with lighting units 211a, 211b, and for indirect lighting by means of the indirect lighting modules 40, 40a, the rail lighting system provides a specially designed adapter unit 7, 7', 7". dimensions and the attachment in the second area 5 and the contact with the conductor device

6, the adapter units 7, 7′, 7″ are designed essentially analogously.

Thus, for example, a first adapter unit 7" is preferably used for a lighting arrangement with indirect lighting modules 40, 40a and a second, independent adapter unit 7 is used for additional directly illuminating lighting modules 11, 11a in the rail 3", for example next to the first adapter unit 7". For the combination of the indirect light modules 40, 40a with an assembly 2 with the low-voltage rail 9, a second adapter unit 7' can be used in addition to the adapter unit 7". Thus, a flexible combinability of direct or indirect lighting components is made possible and at the same time the complexity of the adapter

units 7, 7', 7" are limited in terms of electrical and control technology.

Furthermore, the rail system can have an independent, not shown in the figures

Provide a gigantic adapter unit for radiators or “spotlights” that are not shown.

It is conceivable, for example on the adapter or coupling unit 7" at the same time contact elements 17a for the supply of an indirect light module 40 and contact

telemente 17 to provide for the supply of modules 11, 11a. It would be analogous

conceivable to provide contact elements 17a for an indirect module 40 on the adapter unit 7'. In such a modification, instead of two adapter units, only one is required, which, however, is more complicated in terms of electrical and control technology, especially if direct and indirect lighting

should be controlled independently of each other.

The adapter units 7, 7" described above can each be equipped with different numbers of contact elements 17 or 17a. For example, the adapter unit 7 or 7" could have three or four selective contact elements 17 or 17a, in which case a corresponding number of contact elements

th 18 or 47 can be provided.

For example, three pin contacts 17 or 17a can be used in variants and exemplary embodiments to create the possibility of a so-called “tunable white”, with the pin contacts 17, 17a providing positive and negative current contacts for this purpose. In this case, the contact elements 17, 17a can have the following assignment: first contact element positive (cold); second contact element positive

(warm); third contact element negative.

In a variant in which the "Tunable White" option is not available, it may be sufficient to provide the adapter units 7, 7" each with only two contact elements, with the assignment: first contact element positive, second contact

clock element negative.

A rail lighting system is thus described above which has a combinable receptacle for displaceable spotlights, lighting modules and low-current rails, which themselves accommodate further lighting units, in particular in a displaceable manner

can, in a three-phase or five-phase rail

A lighting arrangement 100 according to a further exemplary embodiment and a variant 100' of this are shown in FIGS. 19-24. The lighting arrangement 100 has a rail 109, at least one indirect light module 140 for providing a

Ner indirect lighting, and an adapter or coupling unit 108 on.

The rail 109 is designed for coupling and/or at least partially accommodating one or more lighting units 111a and/or 111b, which are shown schematically in FIG. 19 and can be of different types.

NEN, for example, as linear modules 111b or spots 111a can be formed.

The rail 109 has a first area 144 and a second area 125, see the cross-sectional view of FIG. 23. In the inner area 125, lower in FIG Supply of the lighting unit (s) 111a, 111b provided. The conductor device 126 extends parallel to a longitudinal direction L' of the rail 109. Fig. 23, 24 shows that the conductor device 126 has two conductor rails, each with two conductors 126a, 126b, one conductor rail on each side of the inner region 125 laterally within it, wherein the conductors 126a are used to provide the electrical current and the conductors 126b are used to provide a control signal, such as a DALI signal, with a control signal based on another protocol or dimming method, for example, also being conceivable. For example, if a control signal is not desired, the conductor means 6 could alternatively be provided with just one

Busbar on one side, and be formed with a total of two conductors.

The rail 109 is designed as a low-voltage or low-voltage rail, for example for supplying power to the lighting units with a DC voltage of less than 60V, for example 48V, which is supplied by a unit (not shown).

feed unit is fed into the conductor device 126.

The adapter unit 108 can also be referred to as a coupling or connection unit, is used to electrically couple the conductor device 126 to the indirect light module 140, can be inserted into the inner region 125 of the rail 109 and can be coupled to the rail 109. In the inserted state of the coupling or adapter unit 108, the conductors 126a, 126b are arranged on the side of the unit 108.

The coupling or adapter unit 108 shown separately in FIG. 20 has a first

Contact device 1130 with contacts arranged on the long sides of the unit 108

clock elements 130 on. The contact elements 130 are arranged and

aims to make electrically conductive contact with one of the conductors 126a, 126b. In addition, the coupling unit 108 has elastically resilient latching elements 131 on its longitudinal sides, by means of which the unit 108 can be mechanically coupled to

of the rail 109 can be clipped into the rail 109 from the visible side S.

The adapter unit 108 is thus set up to tap off current from the conductors 126a and preferably also control signals from the conductors 126b on the side of the conductor device 126 by means of the contact elements 130, by 90° upwards

redirect and make the indirect light module 140 available.

A cross-sectional shape of rail 109 is formed with a web 109a and sidewalls or flanges 109b, with web 109a extending between flanges 109b. The web 109a delimits the area provided with the conductor device 126

permitted inner, second area 125 of the rail 109.

The track 109 is suspended to form the lighting assembly 100, for example in a building, for example by suspending the track 109 from a ceiling, from another component of the building, or from a ceiling

other construction.

The first area 144, also referred to below as the receiving area 144, is arranged on a rear side of the rail 109 which faces away from a visible side S of the rail 109 in the assembled state, and thus on the rear side of the web 3a. The receiving area 144 is formed in the cross-sectional profile of the rail 109 in particular as an upper part of a channel facing away from the web 109a and the inner area 125 . Starting from the opening of the same towards the web 109a, the channel has two sections of different widths and is defined by inwardly projecting

projecting lateral steps towards the web 109a of lesser width. The recording area 144 is used to record an elongated individual

reklight module 140 trained assembly that - in Fig. 23, 24 from above - in the

Recording area 144 can be used. When assembled, this can

the first area 144 used indirect light module 140 light up, so

for example in the direction of the ceiling of the room.

In order to supply the indirect light module 140 with electrical power and preferably with control signals, the coupling unit 108 has a contacting section 108a. The rail 109 is provided with a through-opening 110 in the area of the web 109a, see Fig. 19. When the coupling unit 108 is inserted into the rail 109, the contacting section 109 is inserted and passed through the through-opening 110 in such a way that the upper part of the contacting section 108a passes through the through-opening 110 in order to supply the indirect light module 140 with electrical power and preferably also with the control signals

take care of.

The indirect light module 140 has a double-sided circuit board 141 . On a main surface of the printed circuit board 141 facing the web 109a when inserted into the receiving area 144, elongated strip-shaped contact elements 147 of a contact device 1147 of the module 140 are formed, which extend parallel to the longitudinal direction L′ and are designed as conductor tracks. On the other, opposite main surface is the circuit board 141 with light generating units

directions, which are preferably designed as LEDs, equipped.

On the contacting section 108a of the adapter unit 108, a second contact device 1128 is arranged with a plurality of, in the example shown three, punctiform, pin or pin-head-like contact elements 128, which consist of a

protrudes from the upper surface of the contacting portion 108a, see Fig. 20.

When the coupling unit 108 is inserted, the second contact device 1128, comprising the contact elements 128, makes electrically conductive contact with the contact device 1147 of the indirect light module 140, comprising the contact elements 147. In particular, each contact element 128 makes contact with one of the web-like

Contact elements 147.

Complex cabling of the indirect light module 140 is not necessary in the described embodiment with the interacting contact devices 1128, 1147; the electrical coupling of the conductor device 126 to the indirect light module 140 is possible in a simple and time-saving manner. The through opening 110 with a relatively small size can be prefabricated in the rail 109 or can be introduced flexibly at the construction site. Thereafter, the indirect light module 140, and possibly further indirect light modules 140a, see the variant of FIG. 22, without great

Ren effort can be inserted quickly, variably and flexibly.

In addition, the punctiform contact elements 128 can slide on the track-like contact elements 147 in the touching state, as a result of which the indirect light module 140 in the inserted state relative to the coupling or adapter unit 108

is slidable.

22 illustrates that in a lighting arrangement 100 ′ according to one variant, the indirect lighting module 140 can form a first indirect lighting module 140 which can be electrically coupled to at least one extension indirect lighting module 140a. For this purpose, the extension indirect light module 140a can be inserted into the receiving area 144 like the indirect light module 140 . In this way, a joint 1414 is formed between the modules 140, 140a, which is not yet completely closed in FIG. At the joint 1414, the modules 140 and 140a can be electrically coupled to one another in order to convey the extension indirect light module 140a via the indirect light module 140 through the unit 108

also to be supplied with electrical energy.

The modules 140 and 140a are controlled and operated according to a master-slave operation, with the module 140a as “slave” being subordinate to the module 140 as “master”. In other words, the extension indirect light module 140a is controlled in accordance with those control signals which the first indirect light module 140 receives from the adapter unit 108 and in accordance with which the

first indirect light module 140 is controlled and operated.

The preferably double-sided printed circuit board 141 ("PCB") of the first indirect light

module 140 allows in the embodiment of Fig. 19-24 not only

Power supply of the module 140, but also interprets control signals, which are forwarded via the contact devices 1130, 1128 and 1147 from the conductor device 126 via the coupling unit 108 to the first module 140, and in this way enables control, for example dimming. The module 140a ("slave") is also controlled in the same way as the module 140 via the front-end coupling with the module 140a. The control signal forwarded by the conductors 126b is evaluated by devices of the first indirect light module 140 ("master"), with these devices, for example, generating an output signal based on the control signal, which is used by module 140 to control the same and also at junction 1414 is forwarded to the extension module 140a for its control. The output signal is, for example, a signal that correlates with the dim level, for example based on pulse width modulation or pulse-pause modulation. the

Modules 140, 140a can thus be controlled via a common address.

The one or more extension indirect light modules 140a can be attached to the module 140 in a connectable manner according to the master/slave principle described above and therefore do not require a separate coupling unit. At least ever

an extension module 140a at each end of the module 140 are conceivable.

It should be pointed out that in a likewise advantageous variant of the

19-24, a cable connection can be provided instead of the contact devices 1147, 1128, analogously to that described above for the contact devices 1017a, 1047 of FIG. The cable connection can be formed, for example, with a flexible cable which is connected at one end to the contacting section 108a and at its other end to the indirect light module 140

is connected and extends through the opening 110.

The rails 3, 3', 3", 9, 109 can each be extruded, for example, from a metal material, for example an aluminum material.

expensive people are processed well.

Although the invention has been fully described above with reference to preferred exemplary embodiments, it is not limited to these, but rather in a variety of ways

and way modifiable.
